Skin-to-Skin contact (Kangaroo care) promotes self-regulation in premature infants: sleep-wake cyclicity, arousal modulation, and sustained exploration

The effect of mother-infant skin-to-skin contact (kangaroo care, or KC) on self-regulatory processes of premature infants was studied. Seventy-three infants who received KC were compared with 73 infants matched for birth weight, gestational age, medical risk, and family demographics. State organization was measured in 10-s epochs over 4 hr before KC and again at term. No differences between KC infants and controls were found before KC. At term, KC infants showed more mature state distribution and more organized sleep-wake cyclicity. At 3 months, KC infants had higher thresholds to negative emotionality and more efficient arousal modulation while attending to increasingly complex stimuli. At 6 months, longer duration of and shorter latencies to mother-infant shared attention and infant sustained exploration in a toy session were found for KC infants. The results underscore the importance of maternal body contact for infants' physiological, emotional, and cognitive regulatory capacities.     

Consequences of stereotype suppression and internal suppression motivation: a self-regulation approach

The present research studied the effects of suppression of stereotypes on subsequent stereotyping. Moreover, the moderating influence of motivation to suppress stereotypes was examined. The first three experiments showed that suppression of stereotypes leads to the experience of engaging in self-control (Study 1), to depleted regulatory resources as indicated by worse performance on an unrelated subsequent task that involves self-regulation (Study 2), and to hyperaccessibility of the suppressed thoughts (Study 3). However, these effects were moderated by internal suppression motivation: Increased self-control, depleted regulatory resources, and hyperaccessibility of suppressed thoughts only occur for people with low internal suppression motivation. Furthermore, in line with the argument that depletion of regulatory resources after suppression also should result in increased stereotyping in general, it was found that suppression of a specific stereotype leads to an increased use of stereotypes in general, but only for people with low internal suppression motivation (Study 4).     

Personality disorders in the elderly compared to four younger age groups: a cross-sectional study of community residents and mental health patients

The notion is expressed in the DSM-IV that some personality disorders (PDs) tend to remit with age whereas other types do not. This notion is supported by the literature and the study reported here. Studies published between 1951 and 2000 show that (1) in old age, PDs are prevalent both in normal subjects and to a greater extent in the mentally ill; (2) the evidence for general age-relatedness of PDs is scarce and contradictory; (3) there is evidence for specific age-relatedness of PDs in old age. This empirical study focused on the prevalence of PDs in five different age groups ranging from adolescence to old age. It included both community residents (N = 623, aged 17-87), and mental health patients (N = 315, aged 18-86). Dimensional scores for PDs were assessed by means of the DSM-III-R- and ICD-10- based self-report Questionnaire of Personality Traits (VKP) (Duijsens, Eurelings-Bontekoe & Diekstra, 1996). There was consistent evidence for a specific effect of aging: community residents in the oldest age group reported more schizoid and more obsessive-compulsive characteristics compared to one or more of the younger age groups. Older mental health patients showed more schizoid disorder characteristics and fewer high-energy disorder characteristics compared to one or more of the younger patient groups.     

Stress with parents and peers: how adolescents from 18 nations cope with relationship stress

Background and Objectives: We investigated how adolescents from five regions around the world perceived and coped with parent- and peer-related stress. Design: The study comprised N = 4957 adolescents (mean age of 15.2 years) from 18 countries. Methods: The study used self-report measures for stress perception and coping style. Results: Across countries, adolescents perceived parent-related stress to be considerably greater than peer-related stress. They coped less actively with parent-related stress than with peer-related stress. Significant differences emerged with respect to geographic region and key demographic indicators. Adolescents from Eastern European and Western countries had generally quite low levels of stress. Adolescents from Southern Europe exhibited the highest stress levels and the greatest coping activity in dealing with stress in both domains, whereas adolescents from Southern Emerging and Asian countries reported high levels of parent-related stress and dealt much less actively with parent-related stress than with peer-related stress. Conclusions: Adolescents from all countries were remarkably competent in dealing with relationship stressors. Cultural and regional differences have a stronger effect on stress perception and coping style than gender.     

Implementation intentions: control of fear despite cognitive load

The cognitive consequences of forming implementation intentions in controlling fear were addressed in the present study. Participants with an intense fear of spiders evaluated pictures of spiders, pleasant pictures, and neutral pictures under cognitive load. Regulatory control was measured by participants' self-report ratings of the pictures on the Self-Assessment Manikins Scales. Only participants given implementation intentions reported weaker negative emotional responses to the pictures of spiders as compared to participants given a goal intention and to no-goal control participants. Thus, emotional control by implementation intentions was shown not to tax a person's cognitive resources, attesting to the automatic nature of this self-regulation strategy.     

A longitudinal study on transactional relations between parental marital distress and adolescent emotional adjustment

Using a cross-lagged effect model with 3 waves of data from a 6-year longitudinal study with 3-year intervals, transactional relations between parental marital distress and adolescent emotional adjustment were examined. The sample consisted of 531 parent-adolescent dyads. Results showed that marital distress as reported by parents and emotional adjustment as reported by adolescents were reciprocally related in a transactional model over time. This was principally true for girls and for late adolescents and young adults. For older adolescent girls, an almost full transactional model was found, whereas associations between marital distress and emotional adjustment were less strong for younger girls and were absent for boys.     

A meta-analysis of empirical studies of weight-based bias in the workplace

For nearly 30 years researchers have investigated how bodyweight affects evaluative workplace outcomes, such as hiring decisions and performance appraisals. Despite this, no meta-analytic review has been undertaken to quantify the negative impact that bodyweight has on such outcomes. The results of this meta-analytic study suggest that in relation to non-overweight individuals in the workplace, overweight individuals may be disadvantaged across evaluative workplace outcomes (d = −.52). Further, differences in magnitude of the effects of weight-based bias were found for hiring (d = −.70) and performance (d = −.23) outcomes.     

Recipient design in tacit communication

The ability to design tailored messages for specific listeners is an important aspect of human communication. The present study investigates whether a mere belief about an addressee’s identity influences the generation and production of a communicative message in a novel, non-verbal communication task. Participants were made to believe they were playing a game with a child or an adult partner, while a confederate acted as both child and adult partners with matched performance and response times. The participants’ belief influenced their behavior, spending longer when interacting with the presumed child addressee, but only during communicative portions of the game, i.e. using time as a tool to place emphasis on target information. This communicative adaptation attenuated with experience, and it was related to personality traits, namely Empathy and Need for Cognition measures. Overall, these findings indicate that novel nonverbal communicative interactions are selected according to a socio-centric perspective, and they are strongly influenced by participants’ traits.
